Summary

We have constrained the age of the Nussbaum Gravel at Baculite Mesa, CO using cosmogenic Al-26/Be-10 isochron burial dating. Two samples, a coarse sand and a fine gravel, were prepared for burial dating at the Reston Cosmogenic Nuclide (RECON) Lab and measured via accelerator mass spectrometry at the Purdue Rare Isotope Measurement (PRIME) Lab. The results of this work are summarized in the file “BaculiteMesa_SiteLocation_Odom.csv”, which contains site data and burial age calculations; measurements of aluminum-26 and beryllium-10, as well as related data, are located in respective .csv files. We calculated respective minimum and maximum burial ages for the sand (1.25 ± 0.08 Ma and 1.66 ± 0.12 Ma) and gravel (1.44 ± 0.26 Ma and 2.17 [...]
